This is the name of the angles opposite each other when two lines intersect.
What are vertical angles?
100
This is the angle formed when lines are perpendicular.
What is a right angle?
100
A pair of angles inside the parallel lines on either side of the transversal.
What are alternate interior angles?
100
Lines are parallel; A pair of alternate exterior angles measure 75 degrees. This is the measurement of the other pair of alternate exterior angles.

What is an equation with expressions set equal to each other?
200
An angle that measures more than 90 degrees and less than 180 degrees.
What is an obtuse angle?
200
The angles of the top intersection match the angles of the bottom intersection when 2 lines are parallel.
What are corresponding angles?
200
Lines are parallel; an angle measures 42 degrees. This is the measurement of the angle opposite it.
